Arch Linux 為什麼這麼迷人？

Arch Linux 是眾多 Linux 作業系統中的一種，對象是有 Linux 指令操作經驗的「進階使用者」，想要打造更適合自己的環境，例如不同的桌面、視窗環境等，體驗最新的套件。

Arch Linux 只有文字介面，不包含圖形介面。也就是說，當你安裝完 Arch Linux 之後，你會看到整個螢幕黑黑一片，電腦期待著你用鍵盤輸入文字指令。Arch Linux 只提供最基本可以讓電腦跑起來的功能，其他套件都要自己安裝。

成為掌握一切的設計師

Arch Linux 不會裝你不會用到的東西，你會自己親自打造完全屬於自己的電腦。不會有程式任意自動啟動，不會有人強迫你更新。你可以把你的電腦改成任何模樣，同樣你也為你的電腦的易用性和安全性負責。
